Bleaching old rock strictly to kill possible spores?

[musicsmaker]

In regards to acid soaking:

I opted not to with this rock, based on these factors:

1) This rock is going into a fresh new system that can cycle however long it needs to, and I don't want to dissolve 20% of it after I've already had it aquascaped just how I want it.

2) The rock was really clean to start with. The only sign of former life on it was a ton of tube worm/featherduster/vermited snail skeletons, and the skeletal remains of a few encrusting stony corals. There was practically nothing there to dissolve, other than the rock itself.

Sitting it in ro will do virtually nothing... to properly dry and kill stuff on it you should dry it in the sun...

I aqua scaped my rock after it was bleached and acid washed and left to dry. .

Since you opted not to acid wash it, I would cover the sides of your tank with black towels or something to make sure no light gets in while cycling... and don't run any of your lighting either... then select you will be cooking and cycling in your tank and after a couple months it will be perfect...
